  • earth proxima
    They would be the closest worlds beyond the solar system. If there are planets around the double star Alpha and Beta Centauri, they’re a mere 4 light-years distant, a remove so small we might actually be able to send space probes there in the foreseeable future.

  • saturn rings
    For decades, there has been vigorous debate about the age of Saturn’s rings. Are they as old as the planet, or are they relatively new and we’re just lucky to be around at the same time as they are?

  • r2 instrumet
    After 18 months mounted externally on the International Space Station Zvezda module, the European Space Agency Expose-R2 Photochemistry on the Space Station (PSS) experiment was retrieved by cosmonauts during a February spacewalk. The PSS experiment investigated the evolution of organic compounds upon exposure to space radiation.
